#ifndef TX_EXECUTION_PROFILE_H
#define TX_EXECUTION_PROFILE_H
/* The thread execution profile kit is designed to track thread execution time
based on the hardware timer defined by TX_EXECUTION_TIME_SOURCE and
TX_EXECUTION_MAX_TIME_SOURCE below. When the thread's total time reaches
the maximum value, it remains there until the time is reset to 0 via a call
to tx_thread_execution_time_reset. There are several assumptions to the
operation of this kit, as follows:
1. In tx_port.h replace:
#define TX_THREAD_EXTENSION_3"
with:
#define TX_THREAD_EXTENSION_3 unsigned long long tx_thread_execution_time_total; \
unsigned long tx_thread_execution_time_last_start;
2. The TX_EXECUTION_TIME_SOURCE and TX_EXECUTION_MAX_TIME_SOURCE macros are
defined to utilize a local hardware time source.
3. The following routines are called from assembly code:
VOID _tx_execution_thread_enter(void);
VOID _tx_execution_thread_exit(void);
VOID _tx_execution_isr_enter(void);
VOID _tx_execution_isr_exit(void);
4. The ThreadX library must be rebuilt with TX_ENABLE_EXECUTION_CHANGE_NOTIFY so
that these macros are expanded in the TX_THREAD structure and so the assembly code macros
are enabled to call the execution profile routines.
5. Add tx_execution_profile.c to the application build. */
